Do not upgrade your very old PC because it would cost a lot of money. It's cheaper to buy a new computer in such cases because they are easier to upgrade later.
Upgrading the hard drive:
The majority of people do not really need to upgrade their hard disk, unless they use it for playing a lot of music, movies, and games. A 20 GB hard drive is sufficient to keep new office and internet applications, and all your files and data.
A medium sized hard drive would be around 40 GB and the maximum would be around 60 ? 80 GB.
Before upgrading your hard disk it's best to do a complete disk checkup including disk scan, defragmentation, etc or go to www.tube-traffic.com. If you happen to be an average user and need more storage you can add an additional drive to the existing one. Before an upgrade, be sure to back up your files.
Upgrading the RAM:
RAM or Random Access Memory is the short-term memory of the PC. It keeps data that is being worked on now and may or may not be transferred to the hard drive that represents the long-term memory of the computer.
Current processors can perform an enormous number of operations per second. The hard drive, on the other hand, is significantly slower to handle so much information. This is where a high-speed RAM memory comes in. RAM needs a power supply to keep data. Once the power is turned off the data is lost.
Almost all PCs have 64 MB RAM and often 128 MB. If you want to run newer applications on your PC then you must upgrade to 128/256 MB RAM.
A lot of people who upgrade from 98 to Win 2000 discover that their computers lock up very often. This is because they don't have enough RAM.
CPU upgrade:
If you choose this upgrade, you will have faster execution of instructions but it leaves the RAM and hard drive capacity unchanged.
This sis the most cost effective upgrade and can increase the efficiency of your computer
considerably. Seek a professional help before you take a decision.
Motherboard:
Upgrading motherboard is not such a good proposition unless you replace the CPU and the RAM as well to achieve greater performance levels. You upgrade the motherboard either because the current one doesn't support a faster CPU or the CPU requires a different socket. It could be very expensive. Think about buying a new PC.
Ports:
Ports are sockets at the back of your computer where you plug in external devices. Older PCs work on ?parallel? ports. If you need to work a lot on peripherals such as digital cameras, digital camcorders, CD burners, and scanners then you need to upgrade to USB and Fire wire ports if you are not using them already.
Both tend to be cheaper than the ?parallel? and SCSI devices they replace. Always make sure that there are no compatibility problems with other devices in your PC when you plan to upgrade any hardware on your machine.
